It's a wilderness education site now,
with a lot of this kind of old equipment and machinery laying around.

The first set of photos showed the mining stuff.
There is a small town called Jawbone Flats which was the mining camp from the 30s.
(Yes, I signed up for Freerails shortly after my visit.)
They mined gold, lead, zinc, copper and silver.

Here's a second set of photos that show some of the remnants of the sawmill.
It's a couple of miles away from the town.
I read that the logging company gave up on the site because the terrain was too steep,
and they had lost some trucks into the canyon (maybe true; impressive canyon).

Somehow this valley escaped serious logging,
and there are many stands of giant old-growth trees remaining.
